Chances @ Columbia Colleges

I feel like I am in a bit of a weird situation
For Freshman year, I had a 2.2 GPA with no honors at a top 5 private school. Since then, I switched to a different school which is also considered to be reasonably rigorous and have a 3.9 unweighted 4.2 weighted for the past 6 semesters with an upwards trend in each semester (I have taken summer classes with intensive course loads to improve my GPA. My current GPA is probably around a 3.7 weighted and a 3.55 unweighted overall
my ACT composite (first try) is a 35
Math II: 770, Lit: 740 , Chem 780, US History 800, World History 800

my sister is a current student @ Barnard w/ a 4.0
